So this site has recently been the target of CONTACT FORM SPAM. This means that a CONTACT FORM on the web site is being hammered by an automated process to submit content to the form that is really just junk and random letters.
The main ip address of the spammer is 178.238.232.234. and the logs are here: http://daknetworks.com/logs/giga-hosting.biz
I went ahead and contacted the abuse department at giga-hosting.biz, the company responsible for the server and ip address. I'm doubting to get any response but you never know.
I put on CAPTCHA on the contact forms. CAPTCHA is where it makes you spell the funny letters and numbers before hitting submit. You know what I'm talking about, right? Good. Well, unfortunately, in this world it is just about absolute necessary to have one of those on just about every contact form.
UPDATE
And upon sending the message we received the response of "[your email] is_not_yet_authorized_to_deliver_mail_from" message. Basically this means that they are greylisting or DEFERRING any email that comes to them. Our system should automatically resend the message when appropriate.
